The run dir is changed in the module https://github.com/NixOS/nixpkgs/blob/965f3a22ad779fd2b7ceb48d742ba24491fc9bce/nixos/modules/services/databases/neo4j.nix#L56

The config isn't used when running outside the systemd service https://github.com/NixOS/nixpkgs/blob/965f3a22ad779fd2b7ceb48d742ba24491fc9bce/nixos/modules/services/databases/neo4j.nix#L593-L625
